Suggestions:
1) You have added common_desc macro but not used it anywhere. Also, I don't think you need it as this is not generating more than one subpackage.

2) You can use %autosetup macro instead of %setup as
%autosetup -n Shobhika-%{version}

3) You can also add Appstream metainfo file for font. So if you have that as Source2 in spec file then you can add it as
# Add AppStream metadata file
install -Dm 0644 -p %{SOURCE2} \
        %{buildroot}%{_datadir}/metainfo/%{fontname}.metainfo.xml

%check
appstream-util validate-relax --nonet \
        %{buildroot}%{_datadir}/metainfo/%{fontname}.metainfo.xml

then add this file entry to %_font_pkg macro of main package.

4) When you will update spec file, increase release count as 2 and add related changelog entry and submit new SPEC and SRPM urls for further review.

Spec URL: https://copr-be.cloud.fedoraproject.org/results/vishalvvr/shobhika-fonts/fedora-28-x86_64/00759724-shobhika-fonts/shobhika-fonts.spec

SRPM URL: https://copr-be.cloud.fedoraproject.org/results/vishalvvr/shobhika-fonts/fedora-28-x86_64/00759724-shobhika-fonts/shobhika-fonts-1.04-2.fc28.src.rpm


Resolved the issues mentioned above.
