I see your covers have been rejected for quality issues.
Do not be downhearted, I can see that you are on the right track but, you are finding it difficult to source high resolution images etc.
Stick around and pick up a few tips and find out how to get better images or high resolution poster art for your designs.
I am guessing you are French because you have the credits to some of your work on the the front of the cover, this is not something we would expect for this site so try and avoid it.
Like I said stick around and join in the forums etc, if you need help in producing your covers all you need do is "shout" and someone will help you out (IMG:style_emoticons/default/winking.gif
Best of luck buddy....................look forward to seeing you in the forums (IMG:style_emoticons/default/cheers.gif
