1st) 10/10 2nd) 9/10 dont really think the 4th part really fits the rest,imo it would be better on its own. 3rd) 5/10 i dont like it at all. seems empty and bland,kinda rushed. 4th) 8.5/10 really nice,love the lighting and the concept,but its a bit empty on the left,and the top lefthand corner is darker and dries attention away from the rest. 5th) 7/10 its not bad,not a style i find appealing but still nice.BUT..its seems a bit jumbled and the colors slightly clash. Overall they're all good,but tbh completely honest....your current is teh secks ^_^
The Mario Galaxy one could have been a lot better if you took advantage of the whole galaxy concept and played with brighter colors.
