Hello guys I hope you all enjoyed Christmas.

Here is a preview render of what I’m doing atm its for university so I would be very pleased to get some real constructive criticism on this to get it looking a bit more realistic do you think the lightings right? the sky, fog, environment can anyone give me any tips to improve this more! I am have yet to render this out at movie poster size and then do some comp work on it and a some digital painting! Again any tips in Photoshop would be great to here? or any other apps!

Also I have been getting weird artefacts I have asked most people on this forum but allot can’t see this I don’t know either its certain monitors or the render its self? it’s very annoying! but I can see cell like structures they look like large pixels but there not! actually when you increase the levels in Photoshop they look like squares with bevelled edges

I would appreciate the feedback guys!
