Trike for Heroes1.0

We need to make the room a little more child friendly, i have already made a small toy robot but i want to add something else to it. so ive made this,



i know its nothing incredible but im happy with the outcome, it was really simple to make and it only took about an hour of work.

the only challenge i encountered while modelling this trike was the front wheel, i didnt really know how i would approach the modelling of the holes. this is what i mean



as you can see i have succeeded, the way i did this was get the right shape first, add the divisions and then delete half the wheel. the next step was to delete the faces of where i wanted the holes to be, i then selected all the edges around the deleted faces and extrude inwards in the Z axes. i snapped it to the grid and then duplicated and mirrored the geometry. i then merged the vertexes and thats what i got.
