Making progress 
Couple of crits though, his hair looks to much like grass, make it skinnier. And the mudd dosnāt look slimpy/goopy enough.
And to fix the eyes, try just making the eyeball whiter.
Give him irises? Perhaps some blood-shot veins in there? Maybe some pink squishy flesh around the edges?
It gets dark around the bottom because of the high face count and AO. Do you have distances set to on in the AO settings?
Tweaked eyes, made hair slimmer(still looks like grass) and few little tweaks here and there.
Desoto: Thanks enabling distances helped i didnāt know that.
Final?
Hmm now when i look at it, neck looks really weird from back
Iām not sure why anyone would use AO without distances pressed. I canāt remember if it affects render time directly but in my opinion with a little tweeking of the distance factor it always results in a better looking render. I hope your final has a higher sample count however and I do say that it looks much better now, even the eyes! :o
I always use the Distance button. I think it does affect the render time to some extent, but Desoto is correct. It make sit look better for sure.
Great update too Poju. Awesome character design.
You should add some sweat marks to the arm pit area on the shirt and some dirt/grime on the shirt and shorts too.
BgDM
I really love this guy! I admire your technique. Itās of big inspiration for me! Thanks for sharing!
Everything looks great exept for the hair,
if you wanted it to look like it was buzzed, you should add a bunch of short hair.
Great job on the rest
Yes I think the hair needs work as wellā¦ it seems as though if you were to remove it it would look better. Or perhas just a few strands the way Homer has it.
Well here is nera final, i made new arms, rendered it big and notice that elbows are too high %|
There is few other tweaks u folks suggested too
About AO thing i really dont know how it works and what button to press, im one of those Blenderers who just press buttons to see what happens (i alvays press and twek more than one so it is harder to know what made what), but u helped me ther so thanks.
Actually there is still many buttons that i dont have slighest idea what they do, some of them i looked from dictionarry and i still dont know how effect
Anyway here is wallpapersize render:
And this is final
Very nice work!
whats he on about below me :-?
The pupil of the eye is a hole covered with clear tissue, so yes spec.
