Hi AeroZ and welcome to PJ. Lineart is by Krysis. Its important to credit properly. Somehow you have have distorted the lineart. The BG is not needed, remove or use www.iaza.com. The colors are too saturated and not shaded in areas. Maybe its time to use the forum's WIP section. Its OK to be new to the ways of the pixel. We were all there at one time.
Want to give some dough back to all those amazing pixel artists? Donations provide prize money for contests, help cover hosting costs and support new initiatives.
he reshaped it maybe?
I agree, it is a bit distorted
