Very well for first try... Couple of things, thoug:
1. The trunk seems like a spiral too much. It directly gives the observer the secret of building it: Bending wires... In my opinion, a scratchbuilt item has to hide its construction technique, so that make people ask you how you made it. Plus, the curve does not look natural to me. Remedy: I use modelling clay or tile adhesive to cover the trunk when I build trees with wire. Just have a very diluted tile adhesive, almost liquid like water, and dip the trunk in it, let dry, dip it, let dry, dip it let dry, dip it let dry... Until you are satisfied...
2. Not for this tree, but for the trees you may build in the future, consider making the part with the leaves more volumetric. This would enhance the natural look of the overall structure. Remedy: Use longer wires, even add thinner branches after construction. The longer the wires, the more volumetric the tree would be.
3. The foliage looks good to me, but it is everywhere. Leaves grow on thinnest branches on trees growing naturally. So, it is better to glue them on the thinnest and outermost wires of your model.
Do not get me wrong, I like your tree, but I feel it needs improvement and it can be done with small effort. There are many issues to be considered in a model tree, which you have done well, I could only criticize three of these many things.
Keep it up, I would love to see an update on this soon.
