Yuvraj tag: background doesnt fit the render with the signature, and the effects are too distracting.
With those bar things, the background texture is dodgy imo, either have a ncie gradient to make it look smooth, or use textures to give it an effect, thats kinda half half.
first 2 avatars - those filter almost always = ew
sehwag avatar is actually very good. nice composition and effects fit really nicely. KIU
