The Bridge Gatehouse is a long term potential project of mine. I chose it because the reference, painted by the marvelous environment concept artist, Sihun Park (https://www.artstation.com/artwork/3wKyB) is breathtakingly beautiful and will require me to explore the depths of environment art and force me to upgrade my skills in order to do the concept justice.
As a proof of concept that I can work with an artstyle which is very different from what I usually go for, I decided to model only the 'Guardhouse' aspect of the piece. The Guardhouse provides a smaller sample of the whole, while not completely overwhelming me as I only had three weeks to finish it, in parallel with several other projects.
Initially, I did a breakdown of all the individual assets I would need to create for this project. This can be seen in the legend image I've uploaded. After realizing what I had to work towards, I decided that the first step would be to create tileable textures that could be reused throughout the main showpieces of the concept, namely, the Bridge, the Gatehouse and the Guardhouse and all of the sundry props.
Thankfully, this approach worked better than I'd anticipated, as can be seen by the renders of my final piece. I will be working on this project for the foreseaable future.
