From the author's README on Thunderstore

I like this board, you know.

I happen to own a longboard with this art. Yes, it's originally a longboard. But that hasn't stopped me from importing it into the game :3

So, there's some slight flaws with the texture. Mainly:

The texture is a bit crunchy due to the largest resolution I could find being 1500 pixels
It has JPEG artifacting.
I'm not using a clanker to upscale it. Fuck AI.

Hope you like the design <3

Install Omen SaveTheWhales

You need ReSkate and your own copy of skate. on Steam.

Open ReSkateLauncher.exe and go to MODS.
Search for Omen SaveTheWhales and click install. The launcher also installs anything it depends on.
Press PLAY. In game, the MODS tab of the ReSkate menu (Insert) turns it on and off.

Or install it by hand: download the .zip and drop it on the launcher window, or unzip it into its own folder in Mods\ beside Skate.exe.

Maps show up in the ReSkate menu's level list. To join a server running a custom map, you need the same map installed. If the game won't load after installing, see known issues.

skatemods doesn't host or review this mod. The download comes straight from Thunderstore. Only install mods you trust, because scripts can run code.
