For your first low poly tree, this is outstanding. Just one problem.
When you look at the tree, it looks like it’s bending down, reminding me of legs. Maybe add some branches or make the tree less bent. Overall, this is brilliant.
Could you perhaps upload your images to the thread directly you can do this by hovering to the upper left and click “choose file”. Instead of letting users have to open a website in order to view what you’ve created or made?
Whiles it’s a good model for a user just starting off you could try creating variety of leafs so it doesn’t look identical the tree could feature more branches to enhance the quality of design a bit. The leaves could use more work as it seems to repetitive, try making the leaves have a more unique shape.
You can even add a small addition feature vines wrapped around the trunk down to the base just to give it more of a proper look whatever suits your liking:
Overall the tree looks well made for your first tree but the leaves could use some more work because it just looks like there is barely any leaves on it so I suggest making the leaves more bigger and make them different from one another by rotating some and make some bigger because not all leaves are the same.
Blender is pretty confusing just to work on if you’ve never been on it before. But it definitely gets easier the more you use it and get used to it. Just search up some tutorials on YouTube to help you start out.
If it’s your first try we can expect some problems but ill ignore them and give you some advice about how can you be better!
You may make the leaves with fewer parts, that will make the game less laggy and make the tree look better
And you can try new types with the trunk of the tree
looks awesome! Just wondering did you use skin modifier for the branches? If not, that’s a good helpful tool you can use. For the leaves, it’s not bad for the first time, sometimes you can also use decimate modifier on spheres, or use ico spheres and scale! Good job though!
