thx good advice mangust.
This isn't gonna be a full screen mockup, its a project for college where I have to design 3 levels plus starter screen, These levels will be mounted up along with mockups below capturing gameplay. with the correct screen size, with the health bar, lives, time etc (a bit like the original mockup shown below.)

I may be a bit too grainy, but its honestly too late to just scrap it and start over cus im working to a deadline.
I just felt the need to design a snipit of the level, obviously an actual level would be about 5 times longer than this, but my aim was to capture the right atmosphere.. this is actually supposed to be a darker (harder) level, which is slightly more complex.. After im happy with this to a certain degree Im gonna start on a beginner level, which would be much brighter and easier.
well for now I've updated it slightly more, still tryin to tackle any tiling errors.. added more slopes for variety, plus a new plant. trying to work on this as much as possible, but im in work all weekend and theres only so much time in the day..

thx for the comments guys..
