Now with my first art of sonic meeting with doraemon back in 2023, the background from the original art is inspired by the sonic 1 sms/gg background which it dosen't even look like it so that's why i used the mountains from the sonic 1 sms/gg background

Credits:
Sega, Sonic Team for the sonic 2 sprite used
Ancient for the sonic 1 sms/gg background assets
Techokami for ripping the sonic 1 sms/gg background assets
