Yes. It's awful.
The required http: is missing from some rule targets. The canonical URL for the site root should end with a trailing slash.
You should convert all of the rules to use RewriteRule syntax. There can be problems when you mix mod_alias and mod_rewrite code in the same file.
Only capture (.*) if you intend to reuse that backreference.
Delete the <IfModule> containers.
RewriteBase / is the default and is not needed.
The -f and -d checks are extremely inefficient. There are better methods available and these are often discussed in previous threads.
