NOTE: I don't have Photoshop! I'm just using multiple websites I've found. So... Suggesting to do things that require PS won't help. ^.^'

Lol, it's awesome. I dunt has PS or anything.... I just DA Muro.... DX

Looks cool! Nice work without PS! Good luck for the next ones

its actually cool how you just added c4d renders and got a result like that. good job

So what did you actually use to make this?

Looks Great! You should keep making them with those websites, or whatever you use. :)
