Help and advices with keys design

[techdealer]

Hello,

im still a noob with photoshop and in design world... Im currently trying to design some keys of a gadget to add later in a forum as emoticons.

I need some advices and help to design and improve the blue keys with a better rounded border.

Exemple key attached.

I think that they are to much "trapezium" like probably they need to be rounded? The original device is a casio fx9860g. I dont have much experience,as i said with photoshop, so if someone have also some userfull links/tutorials that could help my in this situation will be nice! Or a remake of my blue keys :lol:

perhaps just add a slight gradient of colour, darker at the bottom and lighter at the top.
the font looks fine, but as for the shape, it doesnt look too bad as it is, maybe just add a bit of curve where the sides meet the bottom line

However i could not improve the bue keys much. Could someone try do a remake?
