My minor comment: Skill should be blank. And it should probably look like ___/___ . If this is for BATTLETECH, and not Allpha Strike, you have the piloting and the gunnery to work with. Make a special note of which is which. On the standard Mech sheet, Gunnery is on the left and Piloting is on the right.
If you wanted to, you could put Gunnery/Piloting in a gray on the blanks so that it wouldn't interfere with the number which would be written over top. Something like: Gunnery / Piloting or Gun / Plt
Or! you could have a secondary pilot card with the pilot stat block that can be slid under the Mech Card, much how you'd put enchantment and equipment cards under a creature in M:tG.
