In order:
5 - not a fan of the template, and really doesn't suit Arsenal :S
6 - I love the use of yellow and blue, but I think for an Arsenal away kit there is too much secondary colour, which in this case is blue.
6 - as above.
6 - better than the first three, don't like the collar much though, or the faint lines.
1 - change the team

6 - the sponsor is a little off centre, but you're getting getting better mate.
Decent effort all in all. Kit making isn't easy, admittedly, but keep at it because you are getting better.
If you want to get even better (this is what I do sometimes), study some pre-made kit templates. What I mean is, open up a kit PSD file (e.g. SS'10, then open nike01 or something) and take a look at the use of colours and effects - I think every kit that has a design uses the effects Inner Glow and Outer Glow, sometimes even Stroke. Change opacities until they look good etc. etc.
I think what you need to do is do what I just said ^ there ^, mess around for a week or so then try and go for the kit of your life.
