Dear,
We are very interested in your child health logo, and we found out that you want to make the logo specialize for iTunes purpose? As we can see you are looking for 1200 x 1200px size logo. How about the background? Do you want a full design for the background or just white color background? So the final question that I am going to ask you, for this logo, do you need it specially for iTunes or you want to use this logo at elsewhere later on? Because it is different. If you just need a logo, I don't really think it is good for iTunes design, but if you want to receive a design specially for iTunes, perhaps this design is no belong to Logo style anymore. Kindly advise if you need our design.
