Does anyone know what is wrong with my Acer?

Hi, over the last couple of years my Acer has started to go crinkley and dry on the edges, dont what is wrong with it.
The first photo is what it looks like now and the second photo is a 2 months ago?

 

Hi
I am having the same problem with my Acer – I also had the same reaction last year. I thought the problem might be leaf scorch. The main reason for this happening is when the roots take in less water than it can feed through to the leaves. I find it happens more so when it has been a very hot spell. Wind can also be a cause and as I have it growing in a pot I am getting more selective where it is placed according to the weather. Such a shame if it has to be tucked away, as they are such a rich colour that you want it stood in a prominent place. Good luck!
