Hello leithne!
I'm Prince, a 2D artist from Spain, and I would like to apply to be a character artist in your project. You can find examples of my work in my portfolio web (->) or in my artfight profile (->). I absolutely love character design and working in visual novels; probably the examples that suit best this project would be the CG art I made for Cupid's Bargain (->) or the design of Valentín in my poster's section, both in my portfolio web.
As a reference, regarding prize, a custom design sprite sheet would be 100€ + 15€ the turnaround or any additional outfit, flat colors and very minor shading included. This could vary depending of the complexity of the character, less if the character's been already designed or is a really simple one and more if the design is really intricate. You'll see I'm used to adapt my style to the necessities of each project, so in case you're interested I would love to hear more in deep about what you have in mind (I'm whataprince in Discord).
Thank you for your time and have a nice day :)
