These are ok strict presses. Your grip may be a little wide, but I can't be sure from this angle. You need to get the wrists less bent backward so the bar isn't as far from the wrists. The middle knuckle should be pointed at the ceiling, and and the bar stacked over the wrist joint. Then you'll be able to get the elbows up so the tips are slightly in front of the bar. Lastly, you're locking the bar out a little further back than you need to. Lock it out above the shoulders and get your biceps by your ears.
Consider trying the version of the press that's in the book with the hip action.
