Photorealistic Eye

okay..so ..this is something i did for building up my confidence so that i could draw human figures in future... yeah! i was too scared to try sketching something like this..a realistic picture....but i guess mark crilley's video of "how to draw a photo realistic eye" was good enough to teach me a simple way of sketching realistic pics... actually it's neither easy nor difficult... coz the more u give details the more ur sketch will look good (this is what i realized) 
Honestly my sketch could have been better...so...i will draw it again sometime n will improve
but as usual it was fun to draw an eye !!

anyways Happy Sketching Everyone
