A fantastic, sabtastic sketchbook.
This is really good, the interface is friendly, and the artwork shows some great talent, effort and (some of them) sense of humor.
The overall display and presentation is beautiful, the background image goes well with the theme, and the subtle music is enjoyable too. The fact that you have to manually loop the music and lack of links are a bit of an annoyance, but then again, those are technical issues that I don't think you're to blame for, as programming obviously isn't what you're focusing on.
Most of the art is great, and I must say you have a truly pretty style for both digital and traditional art. None of the pictures displayed show any signs of rushing, and they all seem to have good amount of effort, even the ones that are clearly just quickies, although some pieces really standed out more than others, but all of them are eye catchy.
Rorschach (you misspelled it, Herrmann would be sad): I like the dark shading that matches the vibe of the comic, and it has a good range of gray. The background seems kinda confusing though, it is hard to tell what it is, although it sort of looks like a dock. Either way, it looks like the railing should be facing the other way
Dr. Manhattan: Now this one looks really nice! I like the secondary light source, and the whole 3/4 pose is well done.
Right Hand: Sketching your very own hand is an infinitely awesome technique for drawing hands later on, and this one looks great. The size of the fingers is anatomically correct and everything feels just right.
Monsters Versus Aliens: Nice as a sketch, and that's pretty much it. The motion and foreshortening is ok, but just that, specially on his legs, which look a bit weird.
Crimson Viper: I like this one, the pose and anatomy are nice, and the folds in her clothing are cool too!
Link: This is definitely one of my favorite ones. His expression just YELLS "I'll kick your ass seven times before you even realize what's going on", and the shading is awesome, specially on his hair.
Francis: I don't know if this is on purpose, but his eyes CREEP ME OUT, I think it's like the same expression I get when I realize I startled a which I hadn't seen before.
Trinit... I mean Zoey: For whatever reason, this one happens to be the one I like the least. The whole thing seems almost unrealistic, mostly because of the leg crossing going on. I don't know absolutely nothing about gun, but they look wrong, like some sort of antique pistol.
Sheva: Great foreshortening and perspective. The shading is really cool and the attention to details in her clothing is great (A friend once told me to draw tribal Sheva. Lost 46% of my hair that day. The only thing that could be impove is her face. While the nose, eyes and mouth look pretty cool, her forehead is way bigger than it should be.
Chris: Now this is just GREAT, the musculature is perfect, and so are the folds in his clothing.
Mom: Another one of my favorites, the posing is awesome, and the lighting is realistic and just beautiful. Sad dad is funny too.
Srs Dragon: Interesting, I wonder what this is abou...
Lol Dragon: LMFAO, this one is just awesome. No words to describe it.
OCs: (I wish I could be more in depth, but I'm running out of characters remaining) Frankly, they all seem a bit cliché, however, in a sort of interesting way, specially Mia and Rouge Riujo. Graphically, they are all outstanding though.
Magikarp: Funny, just that. Not amazingly good, but not even remotely bad either.
Gengar: Same as above, but the nails look a bit weirdie.
Samus; Although rough, looks really good, has a tough yet feminine vibe to it!
Quick poses: Good motion and good anatomy, also has that cartoony sort of vibe to some of them
Sabatage: Really cool, probably my favorite one. The anatomy and shading is perfect, and has a challenging look, like, "touch me and you'll be dead"
At this point, I have almost ran out of characters, so I'll just be brief:
Great job putting this together, the quality of the artwork is remarkably good, and you sure don't lack sense of humor, keep working, your stuff is awesome!
