Ill be honest. 5/10.
How to get better look ?
1.) Don't make images bigger and then resize them..
2.) Use fantasy, dont make just texts, basic backround from google.
3.) Add more effects
Basic size forms:
Signatures:
■ 500x150 (best looking)
■ 600x200 (better for transprent texts)
Wallpapers/Backrounds:
■ 1920x1080 - Super HD resolution (fit for most of ppl)
■ If you want it only for your desktop (perfectly fit to the screen you have to know your resolution)
But if you practise, you can be much and much better.. Good luck
