Question! I have planns on openign my commissions soon! but its been nearly 2ish year since my last commish sheet, so i feel like i should update things?

Currently i have stuff like this:
Listed at £15:

- This is a simple posed no shading piece, good for getting a characters design across
- Mostly single character things

Listed at £30

https://www.furaffinity.net/view/51567826/
https://www.furaffinity.net/view/52354829/
- These would be for more complicated scenes characters doing more specific things
- Shaded but very low effort shading
- Multiple characters being +£10 each.
- Plain backgrounds are free but blurry specific backgrounds being + £5

Listed at Probably £40-£50?

https://www.furaffinity.net/view/48802248/
https://www.furaffinity.net/view/43939839/
- Super specific scenes
- I'd try and shade stuff the best i can
- Backgrounds aren't simple and blurry characters interacting with the background/foreground to some degree
- takes a while to do!
- Most likely gunna involve multiple characters

These are the old prices, do you think i need to update them by £5 - £10?
