Hi, very good first effort. You say you plan a spatula and bowl next. A spatula will be a good little project, but a bowl is a totally different affair. To make a bowl, the wood may be ten years old or more (to get the size), and the heart wood in the centre will be very hard indeed. You may find that your crook knife is totally ineffective for making a bowl, if you use the same technique as you did on the spoon.
I just finished a ladle this weekend, and to core out the bowl, I needed to burn the bowl out bit by bit with charred wood from the fire, then use the crook knife on the charred bowl section.
For little spoons like yours, I tend to use hazel or lime wood. Lime wood is preferable as it is easy to carve and contains natural antiseptics so needs no sealing which could leave a nasty taste to some foods.
