Very well done! I really like the colours and the style, but also the (mockup) game content: Trigger-happy as always, the player has just been shooting anything in her way but now is about to find out that not everything that moves is also an enemy.

Thanks for critiquing, fellas. :]

Made changes, still will be tweaking it as I go along.

you should work some of the background hue into the outer rings of the light coming from those flowers, that way it would seem to naturally fade into the BG.

Also the pixels around the back of the characters head look a little jaggedy.

This is pretty nice, but the aliens tentacles and font isnt very readable. Perhaps try using a similar colour to the skin for the tentacles?
