JackieTheDemon's public artworks/3D renderings, gathered across several platforms, I removed most of the SFW ones, deduplicated them and sorted them in reversed time order (newest-to-oldest).
The latest Real-ESRGAN image restoration model was used to upscale (4.0x, as the model was trained for) and restore (denoise, remove JPEG artifacts) the image, 2D drawings and 3D rendering images were treated with different options.
Some of the output file's resolution were crazy huge (over 10000×10000), so those file's final resolution has to be limited to 6K~8K level using Lanczos resampling, this results in 2.0x~4.0x effective scaling.
The Real-ESRGAN took about 5 hours to crunch down all 220+ images on my machine.
All uploaded pics were compressed with lossless PNG format, in compression level 9.

Feel free to re-upload the whole archive elsewhere then share the link, since I'm not sure how long it would stay up in my cloud drive.
Pictures in the archive were compressed using WebP in lossless mode for maximum disk space utilization (nearly 40% reduction compare to PNG with no information loss).
You can use many free image converters to convert them into any file types you like with no quality degradation, I personally like to use XnConvert.
You can also look at them as is, using image viewers like ImageGlass and XnView.
