It was originally intended to be a commission background, but the design got scrapped so I got this babe for myself, polished it a bit and decided to put it into my portfolio, because why the hell not.
All the architecture and interior element designs/3D models are my own (I use SketchUp for modeling), the pillows and cloth are some random 3D-models used as a base with a bit of overpainting (I had a bunch of free models downloaded a while back when I was studying at a Uni as an interior designer, but I rarely use any of the premade assets for my works, especially commercial ones). The background is photobashing (I always use the assets published under Creative Commons license or similar licenses, especially now when I can't buy stock images and packs for photobashing) with some paintower. The nice brushes I used to draw leaves are from LoranDeSore pack (https://www.deviantart.com/lorandesore/art/LoranDeSore-brushset-v-3-600978404) and the watercolor texture I used on top of the image are made by Hibbary (https://www.deviantart.com/hibbary/gallery/1589588/resources).
There are plenty of nice free assets out there, both for Photoshop and CSP, and I think it is important to share this stuff with others, especially knowing that not everyone can afford paying for brushes, textures and stocks. And if you can't afford PS or CSP either there are a lot of software developers who offer their stuff for free, everyone can download Krita and Gimp or other amazing stuff online.
I find it funny when Ai-bros say that artists are gatekeeping (all while fighting with each other over prompts). Like, it literally have never been easier to find tutorials, assets and instruments for your creations.
