well to me it seems realyl dark on my screen, however i have calibrated my screen to that of a printed item (what i see is what i get most of the time). so i think mine is a bit darker than most.
if you want to see what the crits might be of your work, and be able to critique your own work (very good skill to have) thn you coul try to look at my concept artwork, and see what elements make it successfull.
not necisarily think, there is lihght here there must be on mine to. (that is just an imitation type deal)
but what mood is the image trying to portray, and why is that mood achived… then work out what you are trying to portray from your work and think of how that can be done.
it is about communication. somthing with feeling communicates well.
you could make the scene
things like colours can effect this, a lush scene with lush grass, a lush tree, a blue light coming from the hole might work really well. it would change the feeling of the original concept a lot. but it would be making the work your own, portray your own personality. if you are a fan of cartoon style things, then perhaps make it all cartoonish.
i am open for anything, its about making an image you are proud of.
