First for ages I should say...

Its a bit dull. Its not very desaturated nor is it bright, its caught somewhere in between which is making it look boring. Give it some contrast bumps. Really needs a rethink.

Sorry for being overcritical but i hope it helps. Keep at it!

I`m not sure about this one mate. I havent seen you for a long time now and i`m happy that your back now. I`m not sure about the bg mate, looks too simple and dull, you gotta work on the bg more. The colors look nice, render is good and the text is also good IMO. Just fix up the bg and it will be a really good wall, keep it up

In ym opinion, it's quite good but the cicles on the right don't really have a sense, so maybe add something to them like make them glow or something like that. Also, being more creative with the text won't hurt. Good work overall though and again, welcome back!
