I'm sorry to say, Konchuu, but I agree with Koi. Hardly any of my questions were answered enough to even provide a modicum of information, you were unsure of the terminology I was using, and you backpedaled quite a bit. I was willing to consider the offer if I could get enough information, as it would have made for a nice addition to my portfolio. But since, according to what little information I got, the artist would be responsible to the logotype, box design (I assume the back of it, as well, so that would include page layout and composition), along with designing a piece of cover art for something that really doesn't need one in the first place, then it strikes me as far too much effort for what would amount to be a waste of time.
You may be better off asking elswhere, but as Koi has said, you should take the time to draft up a good, solid proposal. Don't just say "Hey, draw me box art!" and then not know what you want. Figure out what you want, draft up a proposal, and present it in the first post. Also, I'd reconsider the image size. The size Koi quoted is really tiny and not, I repeat, not high quality. Let me give you an example of what resolution print artists work at:
600 DPI.
And that is the minimum. For comparison, most web art is 100 to 300 DPI. For my web pieces, I usually work at 200 DPI. A roughly 8 X 12 image scanned at 200 DPI will have a height of well over 2,500 pixels. Now, up the resolution to 600 DPI. The pixel count would be HUGE. It needs to be that way for printing.
So, for future reference, I suggest you do a bit of research prior to taking your proposal elsewhere. Learn the terminology, learn what resolutions are best for what format, and be prepared to deal with artists asking for payment. Have all of your information in the very first post and be prepared to answer each and every single question an artist has.
I'm sorry it didn't work out here and I wish you good luck elsewhere. Just work on your proposal, make that first post count.
