Hello @Paradossa,

Im Heiwa and I will try my best to review your work. From the first look this is down right very good construction as well as texture work. Not only did you follow good constructional guidelines but also have your own skills that contribute to good outcomes. Anything I critique here would be nitpick as these are already really good.

Good work on the Arrows, You have managed to make them 3D with clean lines and different perspective as well.

Similar work with leaves. You have introduced various forms of "waves" to capture different leaves we get in the wild. Good Job on details as well here and amazing work on branches as well. One thing that you can try is extream Foreshortening on branches as you have tried with arrows. This is just one of the few things you can try Additionally but like i said i would not dress this as a 'critique'.

Amazing work with the non-textured flowers / plants. One thing I would like to add here is that additionally adding countour lines horizontally on the cactus since cactus have huge thickness sometimes it's harder to understand how thick they are. Although in your case, the pores and cactus do a very good job as well on showing the direction and mass of the leaves.

The Texured ones are amazing as well. In normal case i would suggest to have less texture for a reviewer to see the construction guidelines clearly but in your case Im confident about it based on other plants.

Really good job.
