I Like your idea. As a piece of artwork I feel it needs a few more elements in there to make it more interesting for the viewer. It looks like you had fun with it though. Just to critique it a bit more, it's cropped a little funky on the left. I would try doing another three hour quickie showing the massive scale of that sea beast against that little guy with the fishing pole. Throw a little perspective in there- having the action coming toward the viewer will make your image more dynamic. Maybe that's not what you want. If you want to just show scale, I'd do a side view like you have here, but to really bring it home, you have to put the rest of the creature in there.
Use underwater reference to your advantage- both for color and lighting.
I hope I've been helpful to you. If you have any questions about what I mean, I'd be happy to respond. Keep up the work. Awesome creature.
You make some good points Snap,yeah the crop job is a tad askew. It just gives me something to keep in mind for my next one. I suppose I could cram the rest of the body in there somehow but it would have to trail off into the background and would most likely look forced. But anyhoo,thanks for the advice and tips..killer cyborg draw btw
fun idea, now that you've got the idea fleshed out give it another go. try several different compositions as thumnails. course if you're tired of it and ready to move on that's fine. but i think you could have a nice peice. post us some revised thumbnails snap had alot of good ideas. right now everything is going kinda horazontal which makes it a little static. kina feels like a side scrolling video game. so i challenge you. if this only took ya 3 hours then spend another half hour doin some small composition studies post em. then give the revised illustration another 3 hours like the first one and see if it's not better. or not ... up to u.
