Avatar, Always a render in avatar doesn't look good try taking HD images from cricinfo and other sites for avatars(if you want any PSD of my avatars, just PM me) then too it looks fine. Signaturere looks good, just try keeping the render full (whole person) in signatures as focal. Text looks good and try some new fonts, you can get them on dafont.com or fonts2u.com. Keep up the good work and keep[ improving step by step, keep in mind that " Practice makes man perfect "
