This was a quick head i did,Please rate and comment out of 10.

I would also like to know what i can improve and any tips to do better ( I use gimp)

not bad, but you really should spend quality time with each head.

I never do a "quick head"

Even for just 10k, i feel i gotta put a certain amount of effort to make it acceptable

But i like the simplicity

Also, the visor isn't too bad either

Thanks

Plus,This was my first hand drawn head so it was okay for me...:P

It's fine.
But need more details on it.
Like more stuffs that let it loosk cool.
Yep,As Dark said dedicate your time on the heads .
Otherwise keep up the good work.

It look good basic head but it would be much better with more details or stronger lines.

and to be honest I don't know what is front side and what back side?

Its pretty simple to see which side is the front....anyways,Thanks for the comments guys i will work on another robot head with more detail and post it
