Illustrator File Cleanup & Shapes

I have four simple logo shape SVG files that need a tidy-up. The priority is fixing the shape work: one object is pasted in as rough raster image and has some unclean edges that need sharpened. There are a few unnecessary layers that I need deleted.

Here’s what I need done:
• Replace or redraw the raster-based shape as a clean vector so lines remain crisp at any size.
• Remove the redundant layers that serve no design purpose, leaving only logically named, well-grouped layers.
• Double-check that all remaining shapes align correctly and follow their intended proportions once the cleanup is complete.

When you hand the files back, I should be able to open them in the latest Illustrator, see an organised layer structure, and scale any shape without pixelation or distortion. If you spot anything else that compromises file integrity while you work, feel free to fix it or flag it.
