Let me see.
Bg:7/10
Render:6/10 bad placement (my opinion)
Borders:6/10 (Sux :S but i used to do borders like this xd)
Text:5/10 (Text is the hardest thing in sigs)
Lightning:7:10 (seems to be good in v1 but improvement can be applied)
Notes: 1: Try to use very small borders white preferably
2: Make text smaller. Smaller text always better
3: Add a gradient in the text like white and light gray
4: Design the whole thing by adding little simple ad-dons like Small dots like explosion or
smth other dunno.
5: Dont stop readint tutorials. By reading tutorials you are learning new things and with the right experience you create your own custom style
