My First Card Declined?

Alright. I have no idea what I am doing wrong here. I made the card 350 x 350, Made sure the writing was legible and yet it is still declined. WTF? They don't tell me anything so I don't know why. Maybe because I drew it completely and didn't use a picture I found on the internet? Is it because "Get Well Soon" doesn't cut it? Maybe it just sucks? Actually come to think of it, it's not exactly a fine piece of work although I'm proud of it :D. I would be fine with any of these if they would tell me. Please in the name of God help me out here! I need to know what I am doing wrong so that I can fix it and have it put on. Maybe I should just post it as a fanart? I don't know but here it is. It's for Shadow Roy and Mephiles the dark because they got sick and I wanted to do something nice for them. Plus, Shadow Roy asked me kindly if I would do it, but I still would have done it anyway :D. Also, this is the first time I ever used Photoshop to create something. Enjoy.
