What if we use it with a positive verb ? 

Yaz artık ?

Sen de gör !!!! 

ok. one formula for you

If we had to formalise this type of compound sentence in your example ;

 In english order 

* I want to see your new shoes.

Subject [I] + V1 [ want] + V2 [to see in infinitive form] + Object [ your new shoes]

 In Turkish order

Subject + Object + V2 in infinitive form + V1 istiyorum 

Ben    senin yeni ayakkabılarını görmek  istiyorum.

Tamam , sor .

Do you know the reply to that ? What should that person say as responce ? 

Artık here functions as an adverb rather than "stressing",  in this context it means "anymore" . On the other hand, it does effect the verb as an adverb. 

"yaz + ma" 

yazma artık ---> Don´t write anymore.

şifayı  kapmak ----> literally "to  get a cure", which means in fact " to get sick " , it looks like it is a contradictive phrase, however, at present day  we use it in opposite meaning which is " to get sick"

Şifayı  kaptım [kapmışım] ---> I am ill. 

parmak  ısırtmak  ---> Literally ; " to make [cause] someone to bite his finger" , which means " to leave (someone) open-mouthed with astonishment;  to cause (someone) to marvel " 

Piyanistin  parmak ısırtan performansı uzun zaman hatırlanacak. 

The astonishing performance of the pianist will be remembered for long time. 

Örümcek kafalı ---> "Spider minded " , this phrase refers to a person who is against new things, a person who is intolerant to changes  and obstinate, dogmatic and narrow minded.

" Söğüt ağacı üzüm verince "
