Regarding your lucky dip, you sure you don't want to add any kind of stimulus or anything for me to go with? I can do it with none, but if there is a certain theme/colour or whatever, I can work it in.
Otherwise, you can leave it all to me and see what happens. Not even I know what will happen. :P
Alright, first of all the border should be removed. Not many people put borders anymore because they say that the tag ends here, and destroy flow. That said, if you can invent some original way to add a border, like one fat bar on the side or something, then you're all good.
Secondly, obvious lack of effects in the tag. Looks like you smudged a background and slapped a render on. You need more effects, particularly over the render so he blends in more.
That big curved thing to the left is a no, it is stealing my focus away from the render, and the flow of it is going the wrong way anyways.
Not a fan of the black and white, probably would've looked nicer in colours, but maybe because it's so empty at the moment, with effects the black and white could work.
Anyways, background is alright, but you should've smudged the other way so the flow is going from bottom left to top right (like this /).
Not a bad start, but definitely needs more work to improve it.
