Here are a few constructive criticisms in regards to your England and Sweden home kits.
England:
The England badge needs to have the word England above it and a World Cup Star above that. The captain's armband has the England badge on it, not the word 'captain'. There isn't a stripe on the arm, it is rather just a small tick at the bottom of the sleeve (or in the middle in the case of the long sleeved shirt), it is similar to the ones on Nike shirts. The line on the right short isn't that large, it is similar in size and shape to that of the long piece of the cross on the shoulder. Finally there isn't a red line on the socks but rather a thin navy blue line at the top of the socks, it is a semi circle as well so the line isn't at the front. Back of sock -> C <- Front of Sock. I hope that made some sense. The lines on the shorts and at the end of the sleeves also follow this pattern.
Sweden:
I don't know much about the Sweden kits but I'll try to explain to the best of my knowledge. It is almost identical to the England kits varying only in colour and a few minor details. For example the cross of Sweden, which you have placed, on the right shoulder should be on the left. On the right shoulder there is a thin line.
Other than that you are doing very well for you first few kits keep up the great work. I hope you don't mind my constructive criticism.

Sweden does not have anything on the arms like England do also. Your shorts for Sweden are fairly accurate; just make the lines a bit thinner.
