proplem in exporting pixel desing to pdf

Shahad,

If you must add raster elements to vector artwork and have it work tolerably, you will need to use a far higher resolution, sufficient for the final use whether print or screen.

This is based on my loking at two of thew attachments, the first Misk art one and the first Screenshot 2024 one.

It is far easier for helpers to help if you use the Insert Photos button at the top of the Post/Reply box (looks like moon over mountains) rather than the attachment suggestion under the box unfortunately made more conspicuous by the forum software; with the former all your images appear immediately in your post (and can be directly compared and viewed along with the whole thread by just scrolling), whereas the latter requires each image to be clicked to open in its own Tab with time to load and it is necessary to switch back and forth between the thread and each of the images (in this case switching between 6 Tabs).
