Huh, I wasn't aware that you actually really drew stuff, and not just trolled around pchat every so often. By golly!
The realistic style is nice. I'd suggest you try and continue work in the direction in that image, rather than the anime-ish stuff. God's know we have enough of it, and it also seems more... I dunno, forced, somehow.
As for the cellshading thing, don't be pressured into it. Keep in mind that the reason anime companies use it isn't because it looks good, but because it looks reasonably good compared to the time it takes. If they could afford to shade every frame like this
they probably would, and I'll personally slap anyone who thinks this
is shaded better than this
. That's not to say it can't give an awesome effect (I think it's pops even more on non-anime art), and most notably, it's also easier
to make it to look good than soft shading. I just think it's a shame when good artists limit themselves to it, "because that's what they do in anime".
What I think you need, regardless of which kinda shading you go for, is more contrast (lulz, I tell this to everybody, am I simply the minority?) and more detail in the shading. Use different intensities of shadow and be sure that everywhere there should be any kind of shadow, it has some shadow, not just the major, big round areas. The eyes are set into the skull, shadow. The nose always has a highlight somewhere and cast upon the face shadow elsewhere, unless the light is directly from the front. Hands have shadow, like, everywhere, including in the creases, and if the fingers are bended, it will often vary from joint to joint. Major tots of hair will cast shadow on the underlying and so forth and etc.
Also, in the Delin... Delineate Delegate picture, with the mentioned guy with hair over his eye... The standard convention is to still draw the eyes, but cover it fully with the hair color, no opacity or anything. The green in his eye kinda makes it look like the eye is in front of the hair. Personally, I just don't draw the eye, if something overlaps it, the end.
