Specifically, the last stroke in the ほ should start at the top horizontal stroke.
I have terrible handwriting, so I probably shouldn’t judge others’, but…
- さ, き, そ and ふ all look a bit different in handwritten style – it’s a bit hard to describe, but in each case, one of the strokes is done as two, with a break in between.
- The second stroke on the い should be a little smaller (otherwise it risks looking like a り).
- The dash on the か should be to the right of the character (otherwise you risk confusing it with a や)
- う, し and つ need to curve a bit less sharply
- The dash on the む should be a littlefurther to the top-right
- The first stroke on the ら is more of a dash than a bar.
- The る and ろ need to finish a bit further to the left. Also, be careful to make them different – it looks a little like you’ve started to draw a loop on the ろ and then changed your mind.
- れ and わ should loop up and out more.
Some of these might be kinda quibbles, but penmanship is seen as rather important in Japan.
