Improve shopify site speed optimization and simple change css styling

this is my site: [login to view URL] Shoptimized theme. Everything needs to stay the same. Reduce white space, make it a more compact, more professional looking site. Menu backgrounds, improved product looks. Better, larger fonts, more colors. Improved marketing look. Logo - need to improve logo, good concept as it is right now, but need modifications to make it look better. Existing logo with cartoon characters is good, just need to make it better - [login to view URL] - i like logo in [login to view URL] Speed - I need speed the same as in [login to view URL] Better colors, more colors, need orange, pink, white, purple etc… colors. Better fonts. I like logo font in [login to view URL] Collections: Need to create better look for product boxes. Improve look. Better font. Better, more appealing price, sale tag, price that’s higher scratched off (30-50% higher, random in liquid). Bold title for products. Bold price. Improved button. Orange color button. Collections are handled by the app, not the original in theme. Product Filter & Search app - [login to view URL] Collections: Needs short and long descriptions. Short description goes on top of the collection above products. Long description goes below page numbers, below products at the button. The way it's done is using Metafields Guru app.s Collections: Bigger page numbers, design around page numbers - boxes. Load more button that load the next page. If it's the last page, load the first page. Products: Make product elements the same as in jack and jill adult site. For example - [login to view URL] - product page moved more the the left with variant images, breadcrumbs and product title on top, everything left aligned. Below product title, review stars (keep the same by ryviu - code is already there, just needs CSS). Below reviews short description, price - just as big as in jack and jill, number input and add to cart button. FREE SHIPPING text, the same as in jack and jill without gift wrapping. Below additional information and product description. Elements for additional information are all there. At the bottom, related products and previous and next. All the code is there, just need design. Again, reduce white space.
