Drawing Blemishes in Photoshop?

My question is simple. My skins are now turning out ok because I'm able to blend well using partially transparent colors and brushes. However, I am at a predicament, I have a chest with lighting and such, but, how do I draw blemishes and contortions to represent muscle?

Here is a portion of my skin that I need to figure out how to add depth to (cause, as you can see, it's looking pretty fugly at the moment):

(Yes, this skin is for the Ghoul Model. Also, if this is the wrong section, please move and note so I can post in the right section in the future)

this would be most appropriate in WIP skins/textures, actually.

What exactly are you trying to ask? i couldnt quite figure it out.

Moved.

Alright, I'll keep it in mind to stick it in WIP Skins and stuff then.

I looked around for tutorials, but I couldn't find any that address the issue of drawing pieces of flesh and muscle, and that's my question. How do I draw muscles on a skin? Like, what kind of colors of transparent brushes should I use to start blending in blemishes into the skin?

I don't know if this will help any more or not, but basically take the image on the left here....I blended the colors just for sample, but as you can see, there aren't any indications of muscles in that skin. I want it to show muscles like in the image on the right. What techniques can I use for drawing the muscles?

well actually, this is basic drawing/painting.

What you need firstly is much higher contrast. All you did right there was start with a red face and highlighted some white spots in it. You need to have darker shadows.

I cant tell you a "trick" for making muscles, as far as i know, there isnt any. Its just a matter of drawing them with a certain feel that will look good on a model. I can however give you the advice not to shade with black and highlight with white, its usually better to use colors for shadows and highlights to give a more warm real feel to it. (as you can see in the pic you posted yourself, the shading has a bit of green in there, and the highlights a bit of orange (and pink), wich makes the thing just look a lot more realistic and diverse.

I hope this spam is helpfull to you, but i dont think there is much more anyone can do. Its basically just learning how to paint digitally.

Thank you for your help. I'll try using some different colored brushes :)

That actually helped me, thanks Erwt!

Yar, never highlight red with white unless you are Tim and love the pink!

I know. That was just an example :-P

But of course, now I'm using multiple shading and getting better depth. I'll probably post another pic (with the full skin) so you people can point and laugh and, if you want, mention more techniques to help me improve.

FYI in advance, I haven't smudged, blurred, dodged, OR burned anything on this image.

use cnp..its the answer to everything

shut up falco!
