dimensions 120mmx120mm ?

Oh, thanks for asking!

iTunes asks that the size be 3000 x 3000 pixels

the problem is while you're asking for a 3000x3000 px submission because that is what itunes rquires, design crowd allows upto 1500x1500 px submissions, unless i'm missing something here or am mistaken

Make your work with proper size BUT upload a small preview to show client what you are doing.
Bigger files will be uploaded if you win the contest.

Oh that makes sense.

Thanks for catching that! And for coming up with a solution for it.

That is what I do but I thought it wise to point out the restrictions in place to the project owner

Did you plan to give feedback?

Oh. yeah. I'll do that now.

You should have feedback in a moment.

I see no comment nor star rating, sorry
