Your work is pretty solid. I think the spec maps could use some work. On the 2nd guy, his skin is looking pretty plastic and there appears to be spec on his jeans which shouldn’t be there. The black wife beater also is too mirrored. You should do the chest asymmetrically since that area usually attracts the most attention. Your texture sizes are large so you can pretty much afford to make the entire character asymmetrical which will let you add much more interest. I also feel like you should take your characters the extra mile and pose them. It really does help bring the character to life and I feel makes a big difference in presentation because the character will have so much more personality than in a static T pose. Also, posing would include a facial expression cuz right now they all are just static blank expressions.
Good work! also I agree spending sometime doing a simple rigg to posse the characters would be good idea 
sarakawa: Yes, you’re probably right about both things. Sadly I have a strange aversion to posing character for some reason. I guess I’ll just have to get over it.
Anyway, here’s another character of mine that I did a few weeks back. I know that he’s not posed, but I’ve moved on to new projects and just want to post the images of him now. The Undead Samurai is the highest tri count model I’ve done so far, weighing in at 14,980. Modeled in Zbrush and Maya. Normal maps produced with XNormal. Textured with Zbrush, Photoshop, and BodyPaint 3D. Retopologized with TopoGun. Crazybump used for extra normal map details. Two 2048 maps for Diffuse and Normal Maps and two 512 maps for specular. Screenshots are straight out of Marmoset Toolbag (no Photoshopping). Wires coming soon!
Great characters, especially love the Rhino and the Ghoul, details and texturing are great. You’ve got some great work there.
Hey all! Been away for a while working on a new game that will hopefully drop soon. Can’t wait to post my new work from it! In the mean time though I wanted to post the wires and texture maps of the zombie guy. Hope you enjoy and I’ll have more soon. Also, I’m looking for a new project to get on so if you are interested just drop me a line and let me know! (My website is on my signature)
Very cool character What do u use for retopo?
I use Topogun almost exclusively. Love that program. No offense to Zbrush, and maybe it’s better now in version 4R2, but the topology was always hard to see in ZB and when I used to try a workaround technique it would crash a lot. This was version 4 btw.
Fun stuff here enjoyed looking around.
